If you like a customized page of search engines rather than dealing with bookmarks (or your memory), Soovle might be the tool for you. Pick your tool, then search.  Soovle starts with a basic set of Yahoo, Google, Bing, Amazon, YouTube, Answers.com, Wikipedia. You can changes these or add more from an engines list that includes Russian and Chinese.  I don’t see a way  to add an engine that is not on the Soovle list.

• As you enter keywords, Soovle fills the screen with suggested queries and shows the top result.  (Doesn’t show well in Firefox.)
• You can save your search queries.
• The saved search box has a link to Google Trends – another way to explore the topic or analyze the keywords.
• Soovle picks up the history of queries for the day done at the engines. (Cannot think of a good use for this.)

Soovle simply directs the search to the target engine. It doesn’t bypass any personalization  that Google or Bing might apply.

Spruse – once a meta search engine that picked up social media is now a technology and news blog with very little content. Innovative search services are really struggling to get enough money to get enough following to survive.

Ixquick Now Encrypts All Searches, Matt McGee, Search Engine Land (Oct 25)
If you really want privacy in search, use the encrypted search at meta searcher Ixquick.
BTW – you can add it to Chrome – see instructions.

Plain and simple – search Google and Bing in one shot at askBoth – and get some results from Twitter too. Results are shown in separate columns on the page. On two detailed queries I ran, Google was better than Bing, on other more general, they were roughly the same.

Spruse is a new meta-search engine that picks up some of the social web. I came upon it by accident. The About page says it came online in January 2011 and that it “searches multiple search engines filtering all un-useful and unwanted results and returning fast and relevant ones. ”

It’s more like an all-in-one in that it provides options to search individual services including delicious, stumbleupon, Linked In, Spotify etc. The Web search looks Google powered.

Yometa – new metasearch engine (Google, Yahoo, Bing) with a visual display – somewhat – results show as pins on a kind of Venn diagram map. Difference from other meta-search engines is that Yometa has an algorithm to rerank the results.
“The top 22 results will be displayed as pins on the three intersecting circles. The top 4 results (as determined by the Yometa algorithm) among these 22 pins will display in the form of bubbles with website information, linked to the pin location.”
Mentioned in Kartoo Closes and Opens the Door for Yometa by Stephen Arnold.
Of interest: “The company developed its approach based on research that showed that 97 percent of search results by the three search engines(Google, Yahoo and Bing) are different and there is only three percent overlap.”
